环境：

master:  eth0:192.168.1.19  eth1:10.10.10.131

backup:  eth0:192.168.1.20  eth1:10.10.10.132

vip1:192.168.1.17

vip2:10.10.10.133

1，双网卡单VRRP实例配置

master：

global_defs {

        router_id Haweb_1

        }

vrrp_sync_group VGM {

        group {

        VI_HA

        }

}

vrrp_instance VI_HA {

        state MASTER

        interface eth0

        lvs_sync_daemon_interface eth0

        virtual_router_id 51

        priority 100

        advert_int 5

        authentication {

        auth_type PASS

        auth_pass 111

        }

        track_interface {

        eth0

        eth1

        }

        virtual_ipaddress {

        192.168.1.17/24 dev eth0

        10.10.10.133/24 dev eth1

        }

}

backp:

global_defs {

        router_id Haweb_1

        }

vrrp_sync_group VGM {

        group {

        VI_HA

        }

}

vrrp_instance VI_HA {

        state BACKUP

        interface eth0

        lvs_sync_daemon_interface eth0

        virtual_router_id 51

        priority 99

        advert_int 5

        authentication {

        auth_type PASS

        auth_pass 111

        }

        track_interface {

        eth0

        eth1

        }

        virtual_ipaddress {

        192.168.1.17/24 dev eth0

        10.10.10.133/24 dev eth1

        }

}

2，双网卡双VRRP实例配置

master:

global_defs {

        router_id Haweb_1

        }

vrrp_sync_group VGM {

        group {

        VI_HA_1

        VI_HA_2

        }

}

vrrp_instance VI_HA_1 {

        state MASTER

        interface eth0

        lvs_sync_daemon_interface eth0

        virtual_router_id 51

        priority 100

        advert_int 5

        authentication {

        auth_type PASS

        auth_pass 111

        }

        track_interface {

        eth0

        eth1

        }

        virtual_ipaddress {

        192.168.1.17/24 dev eth0

        }

}

vrrp_instance VI_HA_2 {

        state MASTER

        interface eth1

        lvs_sync_daemon_interface eth1

        virtual_router_id 52

        priority 100

        advert_int 5

        authentication {

        auth_type PASS

        auth_pass 111

        }

        track_interface {

        eth0

        eth1

        }

        virtual_ipaddress {

        10.10.10.133/24 dev eth1

        }

}

backp:

global_defs {

        router_id Haweb_1

        }

vrrp_sync_group VGM {

        group {

        VI_HA_1

        VI_HA_2

        }

}

vrrp_instance VI_HA_1 {

        state BACKUP

        interface eth0

        lvs_sync_daemon_interface eth0

        virtual_router_id 51

        priority 99

        advert_int 5

        authentication {

        auth_type PASS

        auth_pass 111

        }

        track_interface {

        eth0

        eth1

        }

        virtual_ipaddress {

        192.168.1.17/24 dev eth0

        }

}

vrrp_instance VI_HA_2 {

        state BACKUP

        interface eth1

        lvs_sync_daemon_interface eth1

        virtual_router_id 52

        priority 99

        advert_int 5

        authentication {

        auth_type PASS

        auth_pass 111

        }

        track_interface {

        eth0

        eth1

        }

        virtual_ipaddress {

        10.10.10.133/24 dev eth1

        }

}

3，监控http服务，master恢复不抢占配置(双网卡可参考以下配置)

master:

global_defs {

        router_id Haweb_1

        }

vrrp_sync_group VGM {

        group {

        VI_HA

        }

}

###检查http进程或端口是否异常

vrrp_script chk_http_port {

        script "killall -0 httpd"

#       script "/tcp/127.0.0.1/80"

        interval 1

}

vrrp_instance VI_HA {

        state BACKUP     ###设为BACKUP恢复后不抢占

        interface eth0

        lvs_sync_daemon_interface eth0

        virtual_router_id 51

        priority 100

        advert_int 5

        nopreempt       ###表示不抢占

        authentication {

        auth_type PASS

        auth_pass 111

        }

virtual_ipaddress {

        192.168.1.17/24 dev eth0

        }

###执行以上命令

track_script {

        chk_http_port

        }

}

backup:

global_defs {

        router_id Haweb_1

        }

vrrp_sync_group VGM {

        group {

        VI_HA

        }

}

vrrp_script chk_http_port {

        script "killall -0 httpd"

#       script "/tcp/127.0.0.1/80"

        interval 1

}

vrrp_instance VI_HA {

        state BACKUP

        interface eth0

        lvs_sync_daemon_interface eth0

        virtual_router_id 51

        priority 99

        advert_int 5

        authentication {

        auth_type PASS

        auth_pass 111

        }

virtual_ipaddress {

        192.168.1.17/24 dev eth0

        }

track_script {

        chk_http_port

        }

}
